Link fence



UNITED STATES EDWARD M. ORANDAL,

PATENT OFFICE OF CHICAGO, ILLINOIS.

LINK FENCE.

SPECIFICATION forming part of Letters Patent No. 241,791, dated May 24,1881.

Application filed April 2, 1881.

To all whom it may concern:

Be it known that I, EDWARD M. GRANDAL, of the cityof Chicago, county ofCook, and State of Illinois, have invented certain new and usefulImprovements in Link Fences, of which the following is a specification.

My presentimprovementhas reference to the construction of that kind oflink fences wherein the links are formed of doubled and twisted lengthsof wire; and its nature will be understood from the followingdescription, reference being had to the accompanyingdrawings, forming apart of this specification, and in which- Figures 1 and 2 are,respectively, plan and side views of a portion of my improved fence.Fig. 3 is a view ofalonger portion thereof upon a smaller scale. Fig. 4.shows one of the links before it has been twisted.

The links A of this fence are formed of single pieces or lengths ofwire, each half of which is doubled upon itself, so as to bring the twoends together at the center and convenient for splicing.Thelinksarecoupled togetherchainfashion at the time of or before beingtwisted, as will be understood from the drawings.

The form of the splice of the ends is not material; but I recommend whatis known as the telegraph-splice, or something analogous to it. Thepoints a a are preferably left looking in such directions that when thelink is drawn out and twisted they will be firmly locked againstuntwistin g by the portion a of the link, which the twist brings upagainst the splice. This fully appears in the drawings.

(No model.)

After the link or a number of links have been brought to the stage ofmanufacture illustrated in Fig. 4, I twist them by any proper twistingmechanism, using at such time, or previously, an amount of tension uponthem which will draw them out to their full length, and they then assumethe appearance given in Figs. 1 and 2, with the eyes a at theirextremities interlocking with the like eyes in their neighbors. I thusform a junction of the links which is scarcely observable in thefinished fence, because it conforms very closely in appearance to theplain twisted portions of the links. When closely twisted, so that theeyes a are contracted, a form of joint is obtained which will not kink.

Whatever of yield under, tension there may be in the splice of the endsof the links is taken up before the twist is completed, so that in thefinished links there will be no more stretch than in the same length offence formed of continuous wires.

I claim The fence composed of the coupled and twisted links A, thehalves whereof are doubled upon themselves and the points spliced at themiddle of the links, substantially as specified.
